Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The work reports the first CVD method for in situ growth of conductive MOFs on metal substrates.
Caveat: The priority claim is author-stated and not independently verified in this extraction.
main p.2, article p.244 · Introduction · Linked to 2 structured results
The Cu3(HHTP)2 NWA symmetric supercapacitor reaches high specific surface area normalised capacitance of 41.1 uF cm-2 at 0.5 A g-1.
Caveat: Normalised value is device/application performance, not intrinsic electronic transport.

The solid-solid interface route can be extended beyond Cu3(HHTP)2, as shown by first-hand preparation of Fe3(HHB)2.
Caveat: Only PXRD and recipe information are provided for Fe3(HHB)2; no conductivity or application data are reported.
main p.7, article p.249 · Supercapacitor performance · Fig. S13 · Linked to 1 structured result
In situ grown Cu3(HHTP)2 NWAs provide better electrode performance than powder electrodes because of good adhesion to Cu, direct electron pathways and lower resistances.
Caveat: EIS resistance comparison is qualitative because no fitted resistance values are reported.

Cu3(HHTP)2 NWA growth is described by a base-growth mode, with continuous c-axis growth while nucleation density remains essentially constant.
Caveat: Base-growth evidence is mainly microscopy-based from time-series and low-density growth figures in the SI.
main p.5, article p.247 · Growth mechanism analysis · Fig. 5; Fig. S6-S8 · Linked to 2 structured results
O2 is required to generate Cu3(HHTP)2 nanowires, while H2O is vital for crystallisation of the nanowires.
Caveat: Based on comparative atmosphere controls rather than isolated kinetic quantification.
